The navigation panel

The navigation panel is located at the left hand side of the screen between the masthead and the footer. It is used to display the menus containing links to information within the information center.

When one of the information classes,  Tasks ,  Concepts ,  Reference  or  Help , is open, the navigation panel contains a list of categories of information within that class. A category can be opened or closed by selecting the "twisty" to the left of the title or by selecting the title itself. Selecting a closed category within the navigation panel causes any other category that is currently open to be closed and the new category to be opened. When a category is opened the topics within the category are displayed below the category heading.

If there is a right-pointing "twisty" to the left of a topic, selecting the topic causes further detail to be displayed. If there is a down-pointing "twisty" to the left of a topic, selecting the topic causes the detail to be hidden. Selecting any topic that is underscored causes the information for that topic to be displayed in the main panel. If the title of a topic is not underscored then it is simply being used as a heading for lower level topics and selecting the topic has no effect.

If either the Home or Advanced search class is open there are no categories of information displayed, but there is a simple list of topics, in the case of the Home class, or a list of searches that have been saved but not deleted, in the case of the Advanced search class.
